Best Way to Study OINA of Muscles

This forum made possible through the generous support of SDN members, donors, and sponsors. Thank you.
Looking at them in an actual body as you study them + repetition. Repeat ad nauseum.
 
Pretty much the same way you learn the enzymes of the Krebs cycle, or the lysosomal storage diseases, or anything else. If anything, anatomy is more intuitive since the action of a muscle gives a pretty big clue about it's O/I.
 
Repetition and discipline. Look at netter's book and visualize at the same time, so you can also almost imagine insertion/origion and also if it was to tug you might get a good idea of the action as well (a lot of times actually).
 
repetition....man one week of med school and I'm already overwhelmed
 
Rather than start a new thread, I thought I would ask here...how much does the OINA stuff for muscular anatomy come up in 2nd year or for boards? Of all things, I just find it kind of boring. I'm hoping that knowing the innervation of the superior gemellus will never come up after the end of this week.
 
so glad my school doesn't emphasize the tiny details on OINAs.
 
Nova Muscle Pro for the iPad is an awesome app if you have an iPad. It does a much better job showing the muscle layers than any atlas. It also has supplementary videos that show you actions, and clearer illustrations that show you insertions and origins. Visualizing it before doing brute memorization is definitely helpful.

Zero attachment questions on my step 1 or step 1 prep questions.

I think you stand a good chance of getting a few innervation questions on boards. Especially brachial plexus and arm disorders (i.e. Erbs palsy, carpal tunnel syndrome).

Action is often helpful for diagnosing complex joints. For example, the shoulder/rotator cuff have muscles with specific actions...they would likely give you a clinical story and assume you could figure out the specific muscle.

In order of importance for boards:
Most important - Specific Named Muscle Disorders (i.e. Erbs palsy) > Innervation > Action > Attachments (useless imo) Least Important

Yes! 👍

Thanks for the info.

No attachments/insertions, period.

In terms of innervation, it was all in terms of pathologies, which were all clearly outlined in FA. I was panicking during studying b/c I was adding all these extra names of other nerve palsies, but I didn't see any of them, and saw Erb's, a median nerve injury, ulnar nerve injury, sciatic nerve injury, peroneal nerve injury, etc.

I would say know innervation in terms of dermatomes and muscles so you can localize the lesion (because some answers on Step 1 will be partially correct)

Innervation is good. Action is "duh". Origin/insertion.... trivia

yea, we are heavy on innervation not so much on origin/insertion. the general idea is good, but we don't memorize each individual muscle's insertion onto specific landmarks on the bone.

You're a lucky man. Test tomorrow and origins and insertions are taking up too much space up in my head.

That sucks.... they are largely worthless. "Name that thing" is not a terribly relevant way to do things. But if someone gets stabbed through the bicep can you tell which distal muscles may be weakened?

Minimally. O/Is -- nothing. Actions -- knowing the actions of muscles around major joints in the limbs helps but there won't be direct questions about them. Innervations -- need to know the basics for the limbs, which is usually a motor deficit and asking what nerve was injured.

Go over them 20 times in different orders.

This

We learned the foramina of the sphenoid from a superior view, and then I flipped it over and learned which foramina corresponded correctly to how I saw them superiorly, knowing that the foramen lacerum is the most medial. Same thing with muscles. Do them in different orders (that way you're not learning the order of muscles, like some learn the ABCs in order, but when asked what comes after K, they have a hard time thinking of it. Origin is simple, because I believe it's always the most medial connection, or whatever is connected closes to the proximal area of the bone: e.g. the insertion of the biceps brachii is the radial tuberosity, a distal part of the arm, in comparison to its origin.

Correct me if I'm wrong. I'm only just getting into muscles as an undergrad in A&P

Tell that to the question writers of my step 1 test.

Definitely not more than a question or two that I remember, but that is fair game for step 1.

Well you should be able to say things like, the biceps flexes the arm, triceps extends, what each rotator cuff muscle does in terms of movement (which is all in FA btw)

At the end of the day, anatomy is such a small portion of Step 1 that memorizing origins and insertions is not high-yield for the exam. That's what I mean when someone asks, "Is this and this on Step 1". While it theoretically might be, it will not be high-yield to focus time studying for that.
 
I'm only a premed but I had to do this in ug. Writing tables worked for me but idk if you have that much time as a med student. Also, if you know the OI then you should be able to at least figure out the action if you don't have it memorized.

Anatomy is obviously low yield on step 1. Apart from the diagrams in FA I didn't really even study it.

My point is that questions will show up and nobody should be surprised when they get a question about the individual action of a rotator cuff or leg muscle.

I wouldn't suggest anyone to "intensely" study anatomy during spring semester of M2 year. However, M1s shouldn't blow it off during anatomy because its something you should learn (and might see again). I'd stay beyond lab practicals you never need to know attachments ever again. I was just making a distinction beyond the two things for those currently taking anatomy.
 
use a skeleton in the lab or buy one and just go through the body muscle by muscle

There's a difference between bizzaro questions and what a typical question looks like.

But yeah I agree with you that no M1 should blow off anatomy. I'm of the persuasion that no one should be studying for Step 1 until the end of 2nd year. Study for your exams and avoid First Aid for Step 1 during M1 and 2 because you're only hurting yourself by never actually learning the material if all you do is read review books.

Though we're all guilty of it, people should avoid falling into the trap of thinking "oh well this won't be on boards, so I won't learn it." It may still be important, so learn it!

I agree (I think you're making the same point I am) that action and innervation are the two parts you should know for Step 1. As for your anatomy classes, if they have told you to learn origins and insertions (which I never had to do for my anatomy class) suck it up and get through it one way or the other.

Well yeah I have been jumping through academic hoops for awhile, pretty sure I can do it for origins and insertions. However now I don't feel as bad about forgetting many of them after the block. I actually enjoy anatomy (lab and learning about disfunction's especially), but memorizing charts with muscle information is not fun.
 
I do not know what atlas you have, but some have color lines showing where the muscle is attached on the skeleton, so the bones are painted. I learned the upper limb without looking at those drawings, and It took me one month to learn it perfect, when I started to look at the drawings it took me maybe half of that time to learn lower limb and trunk , and made things so much clearer.

Point is, do not just try to memorize them from a list, but visualize them while you memorize them. Same thing with the movements they make, if you actually think of the direction of the fibers and where they are attached you dont need to memorize.

Also something that helped me a lot was making my own flashcards, I would take them always in my pocket and test myself when I had to wait for things or in the metro
